' Specification of Letters Patent.

Patented v. 2c, 1921.

Application filed July 12, 1920. Serial No. 395,796.

To all whom it may concern:

Be it known that I, MYRON E. TIBBELs, a citizen of the United States, and a resident of Fremont, in the county of Sandusky and State of Ohio, have made an Invention Appertaining to a Gib-Adjuster; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification. j

My invention has for its object to provide an efficient gib adjusting means which at the same time may be readily removed in case repair is required. The invention is particularly applicable to machines having plungers or hammers wherein the gib is used for guiding the plunger or hammers in their movements. The adjusting means is for properly locating the gib with respect to the plunger or hammer. In the use of adjusting means heretofore known in the art, the adjusting means, by reason of the action of the link or whip-rod interconnecting the crank shaft with the hammer, or by reason of vibration of the hammer, is subjected to heavy pounding or strains and the adjuster requires repair. The gib adjuster commonly used comprises a plurality of bolts which operate to hold the gib in position. One or more of these bolts are pressed against the gib. In the operation of the plunger or hammer the bolt or bolts that press against the gib are upset and the upset end or ends of the bolt or bolts prevent removal and replacement of the bolt without practically disassembling the entire structure. By my invention is provided a means whereby the bolt or bolts requiring replacement may be readily removed from the structure.-

The invention may be contained in structures of different forms and to illustrate a practical application of the invention I have selected a structure containing the invention as an example and shall describe it hereinafter. The structure selected is illustrated in the accompanying drawing.

Figure 1 of the drawings illustrates a side broken view of a hammer which contains my invention. Fig. 2 is a sectional View taken on the line 2-2 indicated in Fig. 1, and Fig. 3 is a sectional view taken on the line 3-3 indicated in Fig. 1.

Referring to the drawings, 1 is a base or gib 3 is provided with Vs that extend into slots formed in the hammer 5 for purpose of guiding the hammer along the gib 3.

The position of the gib 3 with respect to the hammer 5 is determined by the position of the ends of the bolts 6, 7 and 8. The bolt 7 is provided with an eye which engages a pin 10 located centrally with respect to the gib 3. The bolt 7 operates to pull the gib 3 into the channel formed in the side frame 2 by means of the spring 11 which is located between the boss 12 and the nuts 13 that are located on the end of the bolt 7 The bolts 6 and 8 press against the-ends of the gib 3 to push the gib 3 out against the action of the spring ,11. The bolts 6 and 8 extend through nuts 14 located in pockets 15 and when the bolts 6 and 8 are rotated the nuts 14 seat against the outer sides of the'pockets 15 and thus force the inner ends of the bolts 6 and 8 against the ends of the gib 3. The positions of the bolts 6 and 8 are secured by means of the nuts 16 and thus the gib 3 is held in adjusted position with reference to the frame 2 and the hammer 5'by the bolts 6, 7 and 8.

In the operation of the hammer the ends of the bolts 6 and 8 become upset or ham mered down and consequently it is impossible to remove the bolts 6 and 8 without removing the side frames of the structure, except for the fact that I have provided pockets 15 of a suflicient size and so located that the inner ends of the bolts 6 and 8 may be cut with an oxy-hydrogen or acetylene blow torch. In my invention I have also provided openings 19 in the frame 2 that extend from the bottom of the pockets 15 to the outside of the frame which also aids in the removal of the end of the bolts 6 and 8. In the operation of the removal of the bolts 6 and 8 when they have thus been up set, I preferably center the nutsv 14 with respect to the pockets and then cut the bolt between the nut and the inner end of the bolt and again out the bolt so as to remove the nut from the bolt. The severed parts may be removed through the pocket 15. The remainder of the bolts 6 and 8 may then be withdrawn from the side frame 2.

I cleim:-

In a plunger machine having gibs for guiding the plunger member, a, pair of bolts for pressing against the gibs to adjust the gibs relative to the plunger member, a pair of nuts enacting With the bolts, the frame having pockets in which the nuts and the bolts.

In testimony whereof I have hereunto subscribed my name to this speclfieatlon.

MYRON E. TIBBELS.
